Using Dwyer's simple, frictionless Magnehelic gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too

This is a Dwyer magnehelic, the standard against which all others are judged. For a purely mechanical device, this is as good as it gets. I used them by the hundreds in my career, so did not hesitate to buy one when I needed one at home.

This was by far the best gauge I ever bought. Seriously, this thing is awesome. Not only does it compare high pressure air to low pressure air, it does it with style. Just look at those beautiful lines, the graceful curves. The delicate needle is exquisite, and moves ever so subtly when the adjustment screw it tweaked.The printing on the face is crystal clear, and absolutely accurate. It progresses from 0 to 10 impeccably, but also from 0-12! What an enormous value.My only issue, if I had to find an issue, is that the word magnehelic is kind of difficult to say. Magnehelic. Magnehelic. See, it just doesn't feel right.Overall, though, I will definitely be buying more of these. I wish I had more dust collectors to monitor.

It took me a bit to figure out how to configure this meter for my purposes. But, once I got that figured out, it works great. It is saving me a bunch of investigation time in determining what needs to be fixed on brass instruments.
